To clear a warrant, a person can surrender at the detention center on Rock Spring Road, ideally with a lawyer. A no-show at a hearing may be fixable by phone, if the clerk agrees to a fresh date: Circuit Court, 20 West Courtland Street, 410-638-3426; District Court, 2 South Bond Street, 410-836-4545.
